Sight

Sight is a pawn capacity: How well a character can see. Sight affects most colonist stats, with varying impact, though its importance will depend on the pawn's role in the colony. Sight is capped at 100% for many stats, but some combat and medical skills are uncapped.

At the time of writing, the maximum possible Sight capacity in the core game is 250% with a healthy pawn high on go-juice and luciferium with two archotech eyes installed, while also being infected with sensory mechanites. With the Royalty DLC installed, it is possible to reach a Sight capacity of up to a maximum of 325% with the addition of the Focus psycast.

Effects[edit]

Sight has a number of unique interactions with other mechanics, beyond the traditional effects on stats.

At Sight 0% provides +50% psychic sensitivity. As of version 1.5, Blindfold which reduces Sight to 20% or other forms of non-total blindness no longer provides psychic sensitivity bonus.

Pawns with 0% Sight:

Are not subject to the factor from low light levels on move speed or on global work speed.
Will not receive the "Observed corpse" or "Witnessed ally's death" moodlets.^{[Other similar moodlets?]}
Do not gain nor lose any opinion for any other pawn based on their beauty stat.
Do not lose any opinion for disfigured pawns.
Cannot recreate at a telescope, poker table, billiards table, hoopstone ring, books or any type of television. They also cannot skygaze or view art for recreational purposes.
Gain +30% psychic sensitivity if they also have the Blinded with blind psysense precept and both their eyes removed. This stacks with the aforementioned bonus for 0% sight bonus.

Medical Operation Speed	Stat	0.7	1	The speed at which the character performs medical operations.
Medical Surgery Success Chance	Stat	1	1	The likelihood that a colonist will succeed when attempting to perform a surgery. The actual success chance is also affected by factors like facilities, room cleanliness, medicine used, the difficulty of the surgery, and inspirations. No matter how high this stat is, there is always a small chance of failure on any operation.
Medical Tend Quality	Stat	0.7	1.4	The base quality of tending given when tending wounds and illnesses. Final Tend Quality: ( ( ( ( (Medical Tend Quality Stat from Doctor) * (Medical Potency) ) + ( Medical Tend Quality Offset from Bed ) ) * ( 0.7 if Self-Tend) ). Multiplied by a random + or - 25% and clamped to between 0% and the Maximum Tend Quality from the medicine used. Standard bed is not a factor. Only hospital beds have a Medical Tend Quality offset. Light is not a factor of Medical Tend Quality. Light is likely a factor of Medical Tend Speed and Surgery Success chance. Cleanliness is not a factor of Medical Tend Quality. Cleanliness is a factor of Infection Chance. Indoors is not a factor of Medical Tend Quality. Indoors is a factor of cleanliness and thus Infection Chance. Higher tend quality will speed the recovery from injury.
Medical Tend Speed	Stat	0.8	1	Speed at which the character tends to wounds and illnesses.
Melee Dodge Chance	Stat	8	1.4	Chance to dodge a melee attack that would've otherwise hit. Characters will not dodge while aiming or firing a ranged weapon.

Mining Speed	Stat	0.5	1	A speed at which this person mines away walls.
Mining Yield	Stat	0.2	1	The percentage of mined resources a miner will produce. This applies to both wall mining and deep drill mining. This doesn't affect the production rate of rock chunks from deep drills.
Mortar Miss Radius Multiplier	Stat	-1	1	A multiplier on the miss radius of a mortar used by this person. Smaller numbers means more accurate mortar shells.
Plant Harvest Yield	Stat	0.2	1	The yield this person gets when harvesting plants. Low yields give a chance that this person will accidentally waste the harvest.
Plant Work Speed	Stat	0.3	1	Speed at which this person sows and harvests plants.
Reading Speed	Stat	1	1	A multiplier on how fast this person can read.
Repair Success Chance	Stat	0.2	1	The chance that this person will successfully repair a broken down building using a component. Failing means wasting time and resources. Note that this only applies to repairing breakdowns, which is different from repairing damage.
Research Speed	Stat	0.5	1.1	How fast this person performs research and how quickly they can find things using scanning equipment.
Shooting Accuracy	Stat	12	2	Base chance to not miss per cell of shot distance. Chance to hit is also affected by many other factors. A hit chance explanation for any shot can be seen by selecting a shooter and mousing over a target.
Smelting Speed	Stat	0.3	1	The speed at which this person smelts things. Since smelting is dumb labor, smelting speed is not affected by any skill.
Smoothing Speed	Stat	0.3	1	A multiplier on the speed at which this person smooths rough stone floors and walls.

Formula[edit]

The formula for sight is:
Sight = (Base efficiency + Offsets) × Post factors

Base efficiency is the result of combining both eyes efficiencies, with a 75% weight to the strongest eye. There are many way of writing it, but for this section the following will be used:
Base efficiency = (right eye + left eye)/4 + max(right eye, left eye)/2

Offsets are additive with each other.

All factors that affect Sight will be listed below.

Base efficiency[edit]

Eye efficiency. 100% importance, no allowed defect, no max.
- The game assigns 75% weight to the stronger eye and 25% weight to the weaker, so entirely losing a single eye reduces sight by 25% rather than 50%.
- Blindness: 0% part efficiency
- Cataract: 50% part efficiency. Results in −12.5% sight for the first eye affected, −37.5% for the second eye.
- Bionic eye: 125% part efficiency. Results in +18.75% sight for the first one installed, +6.25% for the second one.
- Archotech eye: 150% part efficiency. Results in +37.5% sight for the first one installed, +12.5% for the second one.

Sight	Right eye
Blindness	Cataract	Organic eye	Bionic eye	Archotech eye
Left eye	Blindness	000%	037.5%	075%	093.75%	112.5%
Cataract	037.5%	050%	087.5%	106.25%	125%
Organic eye	075%	087.5%	100%	118.75%	138%
Bionic eye	093.75%	106.25%	118.75%	125%	144.25%
Archotech eye	112.5%	125%	138%	144.25%	150%

Offsets[edit]

The following offsets affect Sight.

Sensory mechanites: +50%
Go-juice: +35%
Luciferium: +15%
Tox gas:
- Mild: −10%
- Moderate: −25%
- Severe: −40%

Post factors[edit]

Blindfold: Sets maximum to 20%
Focus psycast : x130%

Example[edit]

If we were to calculate the highest possible value in unmmoded rimworld, we would have:

Base efficiency:
- Right eye: 150% (archotech eye)
- Left eye: 150% (archotech eye)
Offsets (total +100%):
- Luciferium: +15%
- Go-juice High: +35%
- Sensory mechanites: +50%
Post factors:
- Focus psycast: x130%
